DUMPING RECEPTACLE.

Application filed July 18,

To all whom it may concern:

Be it known that I, FRITZ FiNoKH, residing at Essen, Germany, a citizen of the German Republic, have invented a certainnew and useful Improvement in Dumping Receptacles, of which the following is a specification.

This invention relates to .a dumping receptacle having its floor tiltable toeither side to dump its contents and in which the axis about which the tilting movement takes place lies on the opposite side'of the central longitudinal plane of the receptacle, from that on which the dumping takes place; more particularly stated, the invention consists in a dumping receptacle of the kind described, the floor of which is guided by crossed links in its tilting movement to either side.

An embodiment of the invention in a railway dumping car is representedin the drawing in which,

Fig. 1 is a diagrammatic cross-section through a car in its normal position, and

Fig. 2 is a corresponding View of the car in one of the dumping positions.

To the underframe A of the. car are rigidly-secured the two end walls A paral- The dumping floor B is carried at a plurality of points longitudinally of the car by two pairs of crossed links C, D andE, F, pivotally connected to the underframe A on both sides of the central longitudinal plane, by means of sup porting members consisting of crank-arms G, H, J and K. 'These crank-arms are themselves pivoted to the underframe on both sides of said central plane, the link C, which belongs to the left pair of links, being carried by the crank-arm .G, the link D, which belongs to the same pair, being carried by the crank-arm J, the link E, which belongs to the right hand pair of links, by thecrankarm K, and the link F, belonging to the same pair by the crank-arm H. Thus the crank-arms, G and J or K and H, belonging to the same link pair C, D, or E, F, lie on different sides of the central longitudinal plane of the car. .Both the crank arms K and H belonging to the right hand pair of links E, F, and which turn in the direction of the arrow 00 .(Fig. 2) in dumping, and the crank-arms G' and J, belonging to the left-hand pair of links C, D, and which turn in the opposite direction,

indicated by the arrow '2, in dumping, bear when the car is in the loading position,

against stops a a a or a respectively, provided on the underframe, in which posi tion these crank arms are turned a certain amount beyond their upper dead center position in directions opposite to the arrows a: and y. To each crank-arm K, H and G, J is rigidly secured a crank-arm k 71 for '5 respectively, downwardly directed in the loading position of the car. The crank-arms 70 and h are connected together by a rod L, and the crank-arms g and 2' by a rod M, so that two crank- .quadrilaterals 70 L h and g M '2' are formed.

The inner crank-arms H and J are con-- nected respectively by thrust-rods N and P with operating crank-arms Q and B. These are fast on longitudinal shafts Q and R journalled on the underframe A and lying on the same side of the central longitudinal plane as the correspondin crank-arms H and J. The crank-arms Q and R, which turn in the'direction of the arrows e in dumping, assume when the car is in the loading position, an angular position in which they surpass their inner dead center position by a slight amount, in the opposite directions to the arrows a. The shafts Q and R can be turned b hand levers g and 7*, which are connecte therewith by a clutch mechanism automatically disengaged in the dumping movement in a wellknown way.

Each of the two side walls S of the car is in the loading position of the car, at its lower edge in gravity closed pivotal connection with the floor B in the usual, way which connection is automatically released on the discharge side, during the dumping movement of the floor, while on the other side it is maintained (Fig. 2). At their upper end the side Walls rest in the loading l position of the car, in open bearings a on the end walls A The side walls are guided by links T pivoted on the end walls A Then the car is loaded, the weight of the load is transmitted by the link pairs C, D and E, F, onto the crank-arms G, J and K, H, resting on the stops a 0, 0/ and a and is taken up by these arms. As said arms lie beyond a dead center position, a self-locking action is thus produced.

Since the crank-arms seek to turn in the opposite directions to the arrows y and w under the weight of the load, but are pre vented from turning in said self-locking action, by the stops a a and a a the car is protected against any unintentional discharging in a high degree. In case the crank-arms G, J and K, H are jolted out of their self-locking position by the mo tion of the travelling car and should encounter, at the same time, forces tending to turn them in the direction of the arrows 3 and a2, a further safeguard is provided by the fact that the operating crank-arms of the thrust mechanisms J3, R and Q, N are also in the range of a dead center position and consequently prevent the crank-arms G, J and K, H. from turning in the direction of-the'arrows y and the car is to be dumped to the right (Fig. 2 the left-hand shaft Q is turned in the direction of the arrow 2 by the handlever 9 This movement is transmitted to thev corresponding crankrarm H by each of the" thrust-crank" connections Q, .N, attached to the shaft Q4, and from H to the crankarm K by the crank quadrilateral k L,'Zc so that the crank-arm K is turned in the direction of the arrow at. To assist in an understandingof the dumping movement of the floor B, assume first that one of the links, i. e., the link F, of the pair of links E, F, is removed. The floor then tips, as soon as the crank-arm K is turned past the dead center position in the direction of the arrow 00, towards the right under the effect of the weight of the load, the floor being so guided by the link pair C, D, lying on the left side of the central longitudinal plane, the supporting crank-arms G and J of which remain stationary, that it turns around a mo-- mentary axis lying on the left side of the central plane. If the crank-quadrilateral H, L, 76 were of any customary construction the distance of the pivots, which serve to connect thelink F (at first assumed to be omitted) with the floor B and the crank-arm H, would vary during the dumping movement' of" the floor, so that, with the link F inthe same.

serted,'a movement would only be possible if one ofthe'two pivots were a sliding pivot. But by constructing the crank-quadrilateral h, 11,70 in a suitable manner, it can be'obtamed" that the distance of the. pivots during the dumping movement remains practically When this condition is fulfilled, which should be assumed both for the crankquadrilateral 7L1, 11,70 and"with relation to the link D fer the crank quadrilateral 2' M, 9 the tilting movement of the floor is possible even when the link F is present, as is actually the case, without the necessity of providing a sliding pivot connection as, for example, by the. provision of a. slot.

In the tilting movement of. the floor, the

automatic release of the pivotal connection between the floor B and side wall S takes place in a well known way at the discharg- 1119; side, While on the other side this con- .by the connections Q, N, H, 7L1, L, Z0 K actuated by the shaft Q} and by the links E, F connected thereto.

The dumping to the left needs no further explanation, since the operations correspond exactly to those of the dumping to the right. It may be stated, merely, that, in contradistinction to the first case, the mechanism 1, R R, P, J, 2' M, 9 G on the right, is actuated and the mechanism 9 Q Q, N, H,

7L L, K remains locked.
